Abstract
A three-dimensional object printing apparatus includes a liquid discharge head having a nozzle surface, a moving mechanism that changes a position and a pose of the liquid discharge head relative to a three-dimensional workpiece, and a controller. The workpiece has a first surface and a second surface that forms a corner bent or curved in a convex shape between the first surface and the second surface. When an axis along a scanning direction of the liquid discharge head with respect to the workpiece in a first printing operation of performing printing on the first surface is a first scanning axis and a normal vector of the nozzle surface in the first printing operation is a first discharge vector, the controller controls the driving of the moving mechanism such that the first discharge vector has a component in a direction toward the second surface along the first scanning axis.
